The first beta of what will end up being 6.0 is ready. The betas are 10.12+ only and can be found at the usual links. The betas will self update to the latest betas as we go along (or that is the plan as an updated self updater is also included).

Because this is the first beta you need to manually download this beta to join the betas. Feel free to remove the "Beta" part of the name and use daily, so that we can find all those bugs for the final version.
